I'm doing some work on Edward Field's poems having to do with movies. I'm having trouble figuring out exactly which movies he's talking about in some of the poems in _Variety Photoplays_. I'm specifically interested in the following poems:"Sweet Gwendolyn and the Countess," "White Jungle Queen," and "Nancy" (which is presumably about the comics character but I'm not sure if there's ever been a movie based on her). Can anyone help?
